Sliding Mode Control of a Bidirectional Buck/Boost DC-DC Converter with Constant Switching Frequency

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

Large-signal feedback control of a bidirectional coupled-inductor Cuk converter

Under conditions of order reduction, a nonlinear control of a bidirectional coupled-inductor Cuk converter suitable for large-signal applications is presented. The converter is accurately modeled as a second-order bilinear system and the conditions established for local controllability. The integration of converter state equations and the subsequent introduction of a linear recurrence between t...

LPV Gain-scheduling Control for a Phase-shifted PWM Full-bridge Soft Switched Converter

This paper presents an output feedback LPV gain-scheduling control design for a class of PSPWM full-bridge power converters. The design starts with an averaged model of the converter with adequate complexity. One main contribution of this work is to demonstrate how to reformulate the averaged model into an LPV one. A gain-scheduling controller can then be synthesized taking advantage of the des...

Nonlinear Control for Bidirectional Power Converter in a dc Microgrid

Some comparative studies of several nonlinear control techniques applied to dc-dc power converters are developed in this paper, like for instance the Immersion & Invariance, Passivity-Based Control, Feedback Linearization and the Sliding-Mode Control. All these different control strategies are used to drive dc-dc power converters in a dc microgrid. The load, modeled as a Constant Power Load typ...
